Five lectures in Dornach, June 24, 26, July 1 - 3, 1921 (GA 205)
How do the human organs: heart, lung, kidney, etc., reveal themselves in a person�s psychological makeup? Knowing this, might a person relate to the world out of higher knowledge instead of physically pre-determined tendencies? Particular attention is given in these lectures to the relation of the inner organs to soul activities and disorders.
